Abstract

Rail and road infrastructure projects completed in Denmark, Norway and Sweden between 2008-2022 were generally delivered ‘on cost, over time’. Evidence of delivery to budget over many years stands in sharp contrast to results generally reported in scholarly project management literature and widely amplified. This lack of persistent cost overruns questions claims that the planning fallacy is the root cause of cost overrun and other performance shortfalls, and that optimism bias and malevolent agency dynamics such as strategic misrepresentation are rife.

This research avoids the methodological weaknesses of most prior work by employing data from demonstrably reliable sources, and is transparent about data provenance allowing replication by other researchers.

在成本方面，随着时间的推移：斯堪的纳维亚的交通基础设施如何挑战对项目交付绩效的传统理解

2008年至2022年期间，丹麦、挪威和瑞典完成的铁路和公路基础设施项目通常是“按成本、按时间”交付的。多年来交付预算的证据与学术项目管理文献中普遍报道的结果形成鲜明对比，并被广泛放大。这种持续成本超支的缺乏质疑了计划谬误是成本超支和其他绩效不足的根本原因的说法，以及乐观偏见和恶意代理动态（如战略失实陈述）普遍存在。这项研究通过使用来自可证明可靠来源的数据，避免了大多数先前工作的方法弱点，并且对数据来源透明，允许其他研究人员复制。
